Abstract The present invention discloses a polyester composition resisting hydrolysis, and is characterized by selecting and using macromolecular type end-capping agent which is resistant to high temp. and is not easily volatilized to cap the residual terminal group of polyester so as to raise the hydrolysis-resisting property of polyester and broaden its application field. Said invented polyester composition is made by using polyester with terminal acid group and macromolecular type terminal grup end-capping agent whose content is 0.05-10% by weight of polyester, and said end-capping agent is selected from the functional group of epoxy group and amino group.
